Fat injections (Lipofilling)
The patient's own fat can be used to restore volume to the face
Hyaluronic acid or fat ?
Hyaluronic acid or fat ?
Hyaluronic acid and autologous fat injections are two techniques that treat the same features (face, hands, body), with the exception of breast augmentation as the breasts should not be injected with hyaluronic acid. Both techniques have their advantages.
Hyaluronic acid provides an instant effect without anesthesia directly at the doctor’s office. But its effect is reversible and correction of large volume loss can be costly.
The reinjection of the patient's own fat is 100% natural and can be performed under local or general anesthesia in the operating room. The result is permanent.
Ask your plastic surgeon which option is best suited to you.
The lipostructure technique or Coleman lipofilling involves removing fat by liposuction from areas where there is an excess of fat and reinjecting it into the face. In most cases, excess fat from the knee, when it is present, is used because of its good quality.
Principle of the procedure
The fat removed must be purified by centrifugation, filtration or decantation before being re-injected. The micro suction tubes used are specially designed for the face (microtransfer of fat). All steps take place during the same operation (collection, purification, re-injection).
In most cases, the procedure can be performed under local anesthesia as an outpatient.
For the face, the fat grafting ideally treats :
- increased volume in the cheekbones ;
- correction of dark circles and tear trough ;
- the augmentation of the eyebrow fat pad (Charpy’s pad) ;
- filling hollow temples ;
- correction of flat forehead ;
- augmentation of the chin ;
- filling hollow cheeks.
The rate of engraftment is excellent on the face and limited "over-correcting" is needed. Therefore only a little more fat than necessary is injected to achieve the desired volume. When the loss of fat is greater than expected, a second session several months after the first procedure or additional injections of hyaluronic acid may be necessary.
The result is permanent after the partial reduction phase is completed. However, the volume of fat grafted will fluctuate with any significant weight change.
The advantage of this technique is the natural and definitive characteristic of the fat transfer with no scarring.
Scars induced by lipomodelage are almost non-existent and limited to several 1 mm incisions.
Limited pain is experienced after the procedure, however some swelling and bruising can occur for 2 to 3 weeks.
Risk of complications
As with anysurgery, there are risks of complications although statistically very low.
